Features and benefits

Built tough for demanding digging

Built tough for demanding digging

Features 8% more gross power and 15% more torque than the previous Komatsu model. Delivers 6% more lifting force and 6% more rated load. The combination of exceptional engine power and torque, as well as breakout force, can help boost digging performance in challenging applications.

Engineered to last

Engineered to last

Proven design foundation with an enhanced frame and loader linkage for enhanced longevity. Excellent breakout force helps ensure exceptional performance in tough digging applications. The common components shared with larger Komatsu wheel loaders are proven to help boost overhaul intervals.

Precise and operator-friendly

Precise and operator-friendly

Advanced Joystick Steering System (AJSS) allows precise steering with force feedback integration in the lever motion, matching the machine's steering angle with the joystick's angle. An integrated F-N-R switch, downshift and upshift buttons, and horn button facilitate ergonomic control. The low effort and short-stroke electronic pilot control (EPC) levers facilitate easy operation.

Next-level operator performance

Next-level operator performance

Automatic dig, semi-automatic approach and semi-auto dump systems help boost productivity, especially when V-cycle loading haul trucks. Designed to minimize operator fatigue on long shifts and increase overall efficiency. Automated features help less experienced operators become more adept.

Stay in control in rough terrain

Stay in control in rough terrain

Variable traction control system helps operators maintain traction and reduce tire slippage in slippery or wet conditions. Helps increase tire life. Machine rimpull can be adjusted between 100% and 20% tractive effort depending on conditions, helping operators adjust according to the terrain.

Engine RPM set switch with auto-deceleration

Engine RPM set switch with auto-deceleration

Promote quick cycle times with fast work equipment speeds with throttle lock, an engine feature that sets a constant RPM. When no operator commands are sensed after four seconds, the auto-deceleration feature reduces engine RPM to help save fuel.

Modulated clutch system for smooth operation

Modulated clutch system for smooth operation

Enables quick acceleration speeds, controlled approaches and reduced shock during directional shift changes. The modulation clutch offers elevated control in v-cycle loading patterns while maintaining production efficiency. This control is made possible using the left-hand pedal that modulates tractive effort from 100-20% of the torque converter output.

Smooth ride with bucket stability

Smooth ride with bucket stability

Electronically controlled suspension system (ECSS) absorbs boom bounce and shock on uneven surfaces. This absorption reduces machine pitch and bounces, helping to decrease bucket material spillage and increase ride comfort. Delivers smoother travel performance, even at higher speeds.

Exceptional visibility and maneuverability

Exceptional visibility and maneuverability

A design with standout line-of-sight views from the cab. The 22 bright LED lamps help operators navigate tricky and dark working conditions during night shifts. Delivers enhanced visibility and situation awareness via KomVision — an all-around monitoring system aided by six high-definition cameras.

Time-saving centralized maintenance

Time-saving centralized maintenance

Easy access to key service areas enables your team to perform preventative maintenance tasks efficiently. A centrally located service center provides ground-level access to ports for draining and refilling critical fluids, as well as sample ports to minimize downtime and get your machine back into production.

Smart engine control logic

Smart engine control logic

SmartLoader Logic automatically adjusts the wheel loader's torque output based on the task at hand. This logic helps reduce fuel consumption while maintaining machine performance during varying conditions and fluctuating power needs.

Make informed decisions

Make informed decisions

Komtrax Plus remote equipment monitoring and management system continuously checks your machine’s settings, condition, fuel usage, performance and operating practices. Empowers smart operational decisions based on vital machine telematics information and data. May help you reduce operational costs.
